Nearest whole $ meaning

Hi, my question is when the exam said enter your answer to the nearest whole $, what does it actually mean?

I did an exercise in BPP Kit yesterday, but got the answer wrong because the key of this exercise rounded the answer to the whole thousand $.
The key was: Finance cost for the year = 9,190 x 8% = 735 $’000
=> answer: 735,000$
But 9190 x 8% = 735,2 $’000, so that mean the answer should be 735,200$

Please help me with this confusion so I can avoid the mistake in my actual exam.
Thanks.
